Pretty much everyone who uses a computer plays Minesweeper (or some equivalent on the OS of your choice); most more than they'd want to admit.
But how many people play Zen Minesweeper? This is where you don't use the mark mines option; you just click on the safe squares. The Windows version will detect when the number of open squares on the board equals the number of mines, mark all the open squares as mines, and declare that you've won. I discovered this years ago, and now I never play any other way. Once you get used to it, marking the mines yourself just makes it take longer.
